Abstract (en)
[origin: WO2019197220A1] The invention relates to an acquisition module (10) for a monitoring system of a rotating machine, in particular of an aircraft engine, the acquisition module (10) comprising at least one measurement sensor (11) for measuring an analogue signal x(t) of a physical quantity of a member of the rotating machine, at least one sample-and-hold device (13) configured to collect a sample of the analogue signal x(t) at sampling times t n <i /> and to maintain it constant between two sampling times t n , and at least one memory (16) for storing samples, the sample-and-hold device (13) being configured to collect a sample of the analogue signal x(t) at sampling times t n defined in a random manner, the sampling times t n being defined according to the following law t n = nΔ t + τ n <sb />, the samples and the sampling times t n being stored in the memory (16).
